  • Patent number: 4283971
    Abstract: A power cord end locating device for use with a wire-working station includes first and second pick-up arms that are symmetrically mounted in front of a wire-working station and are movable between an open position and a closed position to sweep an area in front of the machine to locate a power cord end and move the end to and retain the end on a wire-working axis for presentation to the wire-working station. The pick-up arms are mounted in adjacent planes with each arm including first and second arcuate portions that present, respectively, an exteriorly curved and an interiorly curved surface to the wire-working axis. As the pick-up arms move from their open to their closed position, one of the arms contacts the wire end and urges it toward the wire-working axis with the pick-up arms, when in their closed position, holding the power cord end of the wire on the wire-working axis.

  • Patent number: 4241628
    Abstract: A wire stripping machine for stripping the insulation from the ends of a plurality of stranded-core insulated wires and twisting the exposed conductor strands includes upper and lower stripping heads mounted on a support for movement between an open position and a closed, operative position. Each stripping head includes wire separating discs that separate the wires to-be-stripped so that they lie laterally adjacent one another and a stripping element that simultaneously strips the insulation from the ends of the wires and twists the conductor strands. Each stripping element includes an elongated stripping bar having a serrated wire contacting surface and an insulation cutting knife that extends along the length of the stripping bar and presents a cutting edge positioned above the wire contacting surface.
